Under capitalism, a lot of the time, highly dangerous jobs are also highly paid. Kind of a balance that the individual decides to engage with. Same idea behind getting an advanced degree in STEM or law. I think of my job by example, I’m a power plant operator at a large combined cycle plant. No fucking shot I’d be doing this if the pay wasn’t good. I’m around explosive and deadly hot shit all day.
The world as we know it is rapidly approaching the point where it’s going to cease to function. Ecology matters, and climate change is going to wreck the world economy we know and love if war doesn’t wreck it first. Whether hypothetical future better-organized societies should choose to put as much effort into steelmaking as we do seems highly questionable, but it’s up to them.
